TECHNICAL FIELD

The present invention relates to an angle adjuster for a snowboardbinder, and more particularly, to an angle adjuster for a snowboardbinder in which an angle of a binder is adjusted without difficulty andthe binder is conveniently coupled to or decoupled from the snowboardand is firmly assembled to the snowboard.

BACKGROUND ART

In recent years, snowboarding has become one of popular winter sports.The snowboarding is similar to skiing in that a rider rides a snowboardalong a hill covered by snow. The snowboard is similar to a smallsurfboard or a large skateboard without wheels in terms of externalappearance. A person who rides a snowboard (“snowboarder”) locateshis/her feet on the snowboard in a direction perpendicular to alengthwise direction of the snowboard. Like a ski, a snowboarder puts onspecial boots, which are fixed to the snowboard by a binding mechanismfor safety of the snowboarder.

Generally, snowboarders put heir left foot in front of their right footon the snowboard, and desire to adjust a binding installation angledepending on their snowboarding style, technical level and/orpropensity. Also, some snowboarders desire to put their right foot infront of their left foot (so-called goofy style). To meet differentsnowboarding style, technical level or propensity of snowboarders, thebinder is installed in the snowboard so that a snowboard may adjust anangle of his/her feet with respect to a lengthwise direction of thesnowboard.

As shown in FIG. 1, in a conventional snowboard 16, a screw 18 whichpenetrates an adjusting disk 20 on an upper part of a binder 40 islocked to the snowboard 16 to thereby fixe the binder 40 to thesnowboard 16. Uneven parts (not shown) which are shaped like a gear andmate with each other are provided on a lower surface of the adjustingdisk 20 and an upper surface of the binder 40 to control a rotation ofthe binder 40. While the binder 40 is installed in the snowboard 16, thesnowboarder fixes boots 22 to the binder 40 and then snowboards.

However, to adjust an angle of the location of the snowboarder's feet,he/she should unscrew the screw 18 as much as needed and holds theadjusting disk 20 upward to separate the adjusting disk 20 and theuneven parts of the binder 40 and then adjusts the angle of the binder40. Then, the snowboarder puts down the adjusting disk 20 to mate theadjusting disk 20 and the binder 40 and then fastens the screw 18 tofirmly mount the binder 40 on the snowboard 16. Thus, it takes much timeto adjust the angle of the binder 40 and a tool is necessary to unscrewor fasten the screw 18. Also, if the angle of the binder 40 is adjustedin the foregoing manner, the snowboarder should rotate the binder 40with one hand while holding the adjusting disk 20 with the other hand.

The angle adjuster for a snowboardbinder may further include a locking member 140 which is assembled tothe binder 120 and fixes a location of the coupling member 130.

The fixation member 110 is shaped like a circular disk and has a firstlocking part 111 formed on a plate surface thereof. First projectionpieces protrude from both sides of an upper edge of the fixation member110 and second combination grooves 113 are formed in a verticaldirection on an external side in a perpendicular direction of the firstprojection pieces 112. A lower groove 114 is formed in a lower edge ofthe fixation member 110 to communicate with the second combinationgrooves 113. The snowboard B is fixed to the fixation member 110 by ascrew S penetrating a plate face of the snowboard B. The first lockingpart 112 includes a circular hole penetrating a center of the plateface. A diameter of an upper side of the first locking part 112 is largeand a diameter of a lower part of the first locking part 112 is smalland an internal surface of the first locking part 112 is inclined and aplurality of concave and convex parts is formed in a vertical directionin the inclined internal surface.

The binder 120 includes a base 121 which forms a through hole 123 on acenter thereof to insert the fixation member 110 thereinto, a diaphragm122 which is formed in a vertical direction in both sides of the base121, first combination grooves 124 which are formed in a verticaldirection in both sides of the through hole 123, upper grooves 125 whichare formed in the upper edge of the through hole 123 and are connectedto the first combination grooves 124, second projection pieces 126 whichprotrude from a lower edge of the through hole 123 in a perpendiculardirection of the first combination grooves 124, a guiding groove 127which is formed in a vertical direction in an internal surface of thediaphragm 122, and an extension groove 128 which is formed in ahorizontal direction in an upper side of the guiding groove 127. Asupporting shaft 122 a is formed in an upper side of the guiding groove127 and a stopper 122 b protrudes from a lower side of the guidinggroove 127.

The coupling member 130 includes a moving plate body 131 in which aprojection 132 is formed in both sides thereof and is inserted into theguiding groove 127 of the binder 120 and is inserted between bothdiaphragms 122 of the binder 120.

The coupling member 130 further includes a second locking member 132which is formed in a lower surface of the moving plate body 131 andmates with the first locking part 111 of the fixation member 110, and ahandle 134 which is rotatably assembled to an upper surface of themoving plate body 131 and is folded. The second locking part 132 isshaped like a cone whose upper side is cut, and a diameter of an upperside of the second locking part 132 is large and a diameter of a lowerside thereof is small. A plurality of concave and convex parts is formedin a vertical direction in an inclined external surface of the secondlocking part 132 to mate with concave and convex parts formed in theinternal surface of the first locking part 111. Also, the moving platebody 131 preferably includes a transparent material so that a userexamine a locking location of the second locking part 132 and the firstlocking part 111 of the fixation member 110 or to identify a scale of anangle formed in the base of the binder 120.

The locking member 140 includes a rotating part 141 which is rotatablyassembled to a supporting shaft 122 a formed in the diaphragm 122 of thebinder 120, an a pressing piece 142 which extends from the rotating part141 and presses an upper side of the projection 132 of the couplingmember 130.

If the fixation member 111 and the binder 120 include a synthetic resinto process and manufacture a light snowboard, the first projectionpieces 112 and the second projection pieces 126 include a metal plateand are fixed to an upper surface of the fixation member 110 and a lowersurface of the binder 120, respectively, to prevent the coupling areafrom being damaged by an external shock and prevent the binder 120 frombeing separated from the fixation member 110 fixed to the snowboard B.

Hereinafter, an operation of the angle adjuster for a snowboard binderaccording to the first exemplary embodiment will be described.

FIGS. 4 to 9 illustrate an assembly process of the angle adjuster for asnowboard binder according to the present invention.

While the fixation member 110 forming the first locking part 111 on itscenter is fixed to the snowboard B by the screw S penetrating the plateface of the fixation member 110 and the binder 120 having the base 121forming the through hole 123 on its center is arranged in an upper sideof the fixation member 110 as in FIG. 4, an angle of the binder 120 isadjusted so that the first projection pieces 112 of the fixation member110 are inserted into the first coupling grooves 124 of the binder 120and the second projection pieces 126 of the binder 120 are inserted intothe second coupling grooves 113 of the fixation member 110. Then, if thefixation member 110 is inserted into the through hole 123 of the binder120 and the binder 120 is rotated, the first projection pieces 112formed in both sides of the upper side of the fixation member 110 areheld to the upper grooves 125 formed in an upper edge of the throughhole 123 of the binder 110 as in FIG. 6 and the binder 120 is rotatablyassembled to the fixation member 110 to thereby adjust an installationangle of the binder 120.

The second projection pieces 126 protruding from both sides of a lowerside of the through hole 123 of the binder 120 are inserted into thelower grooves 114 formed in a lower edge of the fixation member 110 andprovide strong coupling force by a duplicate coupling structure. Thus,the binder 120 is prevented from being separated from the fixationmember 110 by an external shock.

Particularly, if the first projection pieces 112 of the fixation member110 penetrate the first combination grooves 124 of the binder 120 andare held in part to the upper grooves 125 as in FIG. 7, the couplingstate of the binder 120 is unstable. However, as the second projectionpieces 126 which are formed in a lower part of the through hole 123 ofthe binder 120 are held to the lower grooves 114 of the fixation member110 in a location spaced from the first projection pieces 112, a strongcoupling force is provided even if a part of the first projection pieces112 is held to the upper grooves 125, and safety of the coupling stateimproves.

As in FIG. 6, the coupling member 130 is assembled to an upper side ofthe binder 120 and moves along the guiding groove 127 formed in avertical direction in the both diaphragms 122 and is coupled to thefixation member 110 and controls a rotation of the binder 120. Thecoupling member 130 is coupled to the fixation member 110 if moved to alower part of the guiding groove 127, and is decoupled from the fixationmember 110 if moved to an upper part thereof. In a process of adjustingthe angle of the binder 120, the coupling member 130 is located in theextension groove 128 formed in a horizontal direction in an upper sideof the guiding groove 127 and is prevented from being coupled to thefixation member 110. Then, a user may adjust the angle of the binder 120with both hands. A user moves the coupling member 130 by using thehandle 134 installed and folded in an upper surface of the moving platebody 131 of the coupling member 130.

If a user adjusts the binder 120 to a desired angle by rotating thebinder 120 and moves the coupling member 130 from the extension groove128 to the guiding groove 127 and then in a lower direction as in FIG.8, the second locking part 132 formed in a lower center of the couplingmember 130 is inserted into the first locking part 111 of the fixationmember 110 exposed through the through hole 123 of the binder 120. Adiameter of an upper part of the first locking part 111 is large and adiameter of a lower part thereof is small and the first locking part 111with the foregoing configuration is formed in the center of the fixationmember 110. A diameter of a lower part of the second locking part 132 issmall and a diameter of an upper part thereof is large, and the secondlocking part 132 with the foregoing configuration is shaped like a largecone with its upper side cut and is formed in the lower center of themoving plate body 131 of the coupling member 130. That is, the lower endof the second locking part 132 whose diameter is small is inserted intothe upper side of the first locking part 111 whose diameter is large.Thus, even if the second locking part 132 is not accurately coupled to acoupling location of the first locking part 111, it is efficientlyinserted thereinto. As a plurality of concave and convex parts is formedin the internal inclined surface of the first locking part 111 and theexternal inclined surface of the second locking part 132, the firstlocking part 111 mates with the second locking part 132 and controls therotation of the binder 120.

As in FIG. 9, the rotating part 141 of the locking member 140 isrotatably assembled to the supporting shaft 122 a formed in the bothdiaphragms 122 of the binder 120. When the pressing piece 142 extendingfrom a lateral side of the rotating part 141 rotates in a lowerdirection, the pressing piece 142 presses the coupling member 130 to thefixation member 110 of the binder 120 and prevents the coupling member130 from being separated from the fixation member 110. The pressingpiece 142 of the locking member 140 is guided by the stopper 122 bformed in the diaphragm 122 of the binder 120 to a location pressing thecoupling member 130.

If the binder 120 assembled to the fixation member 110 and mounted inthe snowboard B is to be disassembled, such disassembly process isperformed in a reverse order of the foregoing assembly order. That is,the locking member 140 is rotated to release the coupling member 130.The coupling member 130 is separated from the fixation member 110 byusing the handle 134 formed in an upper side of the coupling member 130.Then, the coupling member 130 is located to the extension groove 128provided in the upper side of the guide groove 127. Then, the binder 120is rotated to locate the first projection pieces 112 of the fixationmember 110 in the first combination grooves 124 and to locate the secondprojection pieces 126 of the binder 120 in the second combinationgrooves 113 of the fixation member 110. If the binder 120 is heldupward, the binder 120 is separated from the fixation member 110.

Hereinafter, an angle adjuster for a snowboard binder according to asecond exemplary embodiment of the present invention will be described.

FIG. 10 is an exploded perspective view of the angle adjuster for asnowboard binder according to the second exemplary embodiment of thepresent invention. FIG. 11 is a lower perspective view of a fixationmember and a coupling member of the snowboard binder according to thesecond exemplary embodiment of the present invention.

As shown therein, the angle adjuster for a snowboard binder according tothe second exemplary embodiment of the present invention is differentfrom the angle adjuster for a snowboard binder according to the firstexemplary embodiment in that it includes a locking member 140′ whichfixes a binder 120 to a fixation member 110 while the binder 120 isassembled to the fixation member 110 and its angle is adjusted.

That is, the fixation member 110 according to the present exemplaryembodiment includes a first locking part 111 which is formed in an uppercentral part of the fixation member 110, first projection pieces 112which protrude from both sides of an upper edge, and second combinationgrooves 113 which are formed in a vertical direction in an external sidein a perpendicular direction of the first projection pieces 112. Thefixation member 110 is fixed to a snowboard B.

The binder 120 includes a base 121 which forms a through hole 123 intowhich the fixation member 110 is inserted, a diaphragm 122 which isformed in a vertical direction in both sides of the base 121, firstcombination grooves 124 which are formed in a vertical direction in atleast both sides of the through hole 123 to insert first projectionpieces 112 of the fixation member 110 thereinto, and upper grooves 125which are formed along an upper edge of the through hole 123 of the base121 to move the first projection pieces 112 of the fixation member 110.The binder 120 is rotatably assembled to the fixation member 110.

While the coupling member 130 is inserted between the both diaphragm 122of the binder 120, both sides of the moving plate body 131 are closelyadhered to an internal surface of the diaphragm 122 to prevent arotation of the coupling member 130. The coupling member 130 includes asecond locking part 132 which is formed in a lower surface of thefixation member 110 and mates with the first locking part 111 of thefixation member 110 and is assembled to the fixation member 110 in anupper side of the binder 120.

In particular, the locking member 140 which fixes the coupling member130 to the fixation member 110 includes a rotating shaft 143 which formsa coupling projection 143 a in both sides of a lower part thereof and afolding handle 143 b in an upper part thereof and is rotatably installedin a center of a moving plate body 131 of the coupling member 130, aninsertion opening 144 which is shaped like a rectangle and is formed ona center of the fixation member 110 to insert the coupling projection143 a of the rotating shaft 143 thereinto, and a space 145 which isformed in an internal area of the insertion opening 144 so that thecoupling projection 143 a of the rotating shaft 143 rotates while beinginserted into the insertion opening 144.

FIG. 12 is a lateral sectional view of an assembly state of the angleadjuster for a snowboard binder according to the second exemplaryembodiment of the present invention. FIG. 13 is a plan sectional view ofan assembly state of the angle adjuster for a snowboard binder accordingto the second exemplary embodiment of the present invention.

As shown therein, if the binder 120 is rotated while the fixation member110 fixed to an upper surface of the snowboard B is arranged to beinserted into the through hole 123 formed in the base 121 of the binder120, the first projection pieces 112 formed in both sides of thefixation member 110 are located in the upper grooves 125 formed in aninternal circumference of the through hole 124 of the binder 120 and thebinder 120 is rotatably assembled to the fixation member 110.

Then, a user adjusts the binder 120 to a desired angle and fixes thebinder 120 to the fixation member 110 by using the coupling member 130to thereby prevent the binder 120 from being rotated. The assemblystructure of the second locking part 132 of the coupling member 130 andthe first locking part 111 of the fixation member 110 is the same asthat according to the first exemplary embodiment of the presentinvention. Thus, detailed description thereof will be omitted.

If the rotation of the binder 120 is restricted by the assembly of thecoupling member 130 as above, the locking member 140′ is used to preventthe coupling member 130 and the fixation member 110 from being decoupledfrom each other.

Referring to the operation of the locking member 140′, a lower end ofthe rotating shaft 143 rotatably provided in a center of the movingplate body 131 of the coupling member 130 is inserted into the insertionopening 144 formed in a center of the fixation member 110 and is locatedin the space 145 inside the insertion opening 144 during a process ofcoupling the coupling member 130 to the fixation member 110.

A rotation angle of the rotating shaft 143 is adjusted so that thecoupling projection 143 a formed in lower sides of the rotating shaft143 penetrates the insertion opening 144 and is inserted into the space145 through the insertion opening 144 during an assembly process of thecoupling member 130 and the fixation member 110.

If the rotating shaft 143 is rotated by approximately 90 degrees byusing the handle 143 b provided in an upper part of the rotating shaft143 while the coupling projection 143 a is located within the space 145,the coupling projection 143 a in lower sides of the rotating shaft 143is interfered with by a peripheral part on both sides of the insertionopening 144 and the coupling member 130 is prevented from beingseparated from the fixation member 110.

After the coupling member 130 is fixed to the fixation member 110, thehandle 143 b formed in the upper part of the rotating shaft 143 isrotated to be arranged in parallel with the moving plate body 131 of thecoupling member 130. Then, the handle 143 b is prevented from beinginterfered with by user's boots and the rotating shaft 143 is preventedfrom being rotated by the handle 143 b while in use.

The locking member 140′ may be released in a reverse order of thelocking order. If the rotating shaft 143 is rotated by approximately 90degrees to separate the coupling projection 143 a formed in the lowersides of the rotating shaft 143 upward through the insertion opening 144in a rectangular shape, the coupling projection 143 at both sidesconforms to the insertion opening 144 and the coupling member 130 may beseparated from the fixation member 110.

Although a few exemplary embodiments have been shown and described, itwill be appreciated by those skilled in the art that changes may be madein these exemplary embodiments without departing from the principles andspirit of the invention, the range of which is defined in the appendedclaims and their equivalents.
